It will thus be seen that'the jar of the upward movement of the' axle is avoided uponthe seat, andl the downward movement thereof, as well as the rebound of the body 16, is taken resiliently by the said springs until the normal relationship between body, seat, and axle, is resumed, thereby resulting in great comfort in riding, and the dash-pots also act as shockabsorbers for the automobile to prevent the very great rebound strain on .the conventional springs 17 and which frequently causes a break therein or thereof. o

As shown in Figs. 4 and 5, I prefer to provide an articulating joint between the axle` 18 and the cylinder 29 by means of a yoke 41 and pivots 42 shown in said figures,

I but I do not limit myself to any specific form ofconnection in view 'of the many different methods of suspending the seat, within the scope of my invention.

In the diagrammatic views, 8 to 15, I have shown the body loadl at 43, the seat load at 44, and lstops 45 to limit 'the relative movement ofthe parts; Fig. 8 is similar to that already described with the difference thatthe dash-pots 29 are connected with thev body instead of with the axle; in` this method, when the vehicle passes over a road inequality, the springs 17 first collapse, and

afterward the springs 21, and, thereafter,- the springs 17 .rst again expand and therel after the springs 21 but lat a speed depending upon the return of the pistons in the dash-pots to normal positions, and the seat remains practically in the same horizontal plane, unaffected by the axle or body movements. Fig. 9 represents a departure in lthat the springs 2l'are eliminated, and the 'springs 46 used on thepiston-rods, between the axle and seat, instead, and the body movement has no effect whatever on the seat, and the axle very little to move it from its normal horizontal plane. Fig. 10 shows' a combination of Figs. 8 and 9, the

front of the seat being supported bythe springs 21 and the rear by vthe springs 46. Fig. 11 shows a combination of 8 and 9, the

seat being supported front and rear by theV springs 21 and centrally by the springs 46. Fig. 12 shows the formshown in Fig. 11 but with the s rings 46 omitted, 'this being the same as in igs. 1 and 2. `Fig. 13 shows a modification 'in that a rigid support 47 is employed for the front edge vof the seat and to which it is pivoted, the structure otherwise being similar to the form shown in Fig. 10. Fig. 14 shows a combination of the forms shown in Figs. 9 and 13, the support 47 being employed. Fig. 15 shows a combination of the forms shown in Figs. 11

and 13, the support 47 being substituted for the front edge springs 21. The effect of all of these forms is substantially the same although it varies in degree in the several forms, and many other modifications thereover will suggest themselves to meet varying conditions of body load, seat load, and roa conditions, the result attained in all the forms being to maintain the seat in approximate parallelism with the surface of the road over which the vehicle is moving, in a general way, with very little if any effect on said seat by the vertical movement of the axle or body because of road inequalities; while the forward edges of the forms where the seats are pivoted will be affected by the movement of the body, the rear edges are so freely movable independently of the body as to produce the desired result.

It will thus beI seen that, by means of my 'zol invention, the upward axle movement does l not affect the seat'in view of the compression of the interposed springs, either directly or indirectly, this axle movement being very rapid; in the downward axle movement the seat has a tendency to follow the same because of the resisted piston movement in the dash-pots, but the springs interposed between the axle and seat, directly or indirectly, counteract this tendency to a material extent but, because of thedash-pots, said sprlngs cannot cause the seat to fly upward in the tendency of saidsprings to rebound after compression, andan approximately constant relationship between thev seat and axle results, with the body balancing itself therebetween; while I state that an approximately constant axle and seat obtains, I use this term to refer to the mean plane of the axle, and not to the movements above or under the mean plane-due tol stones or other road inequalities of abrupt and briefly lasting effect on the axle.

Concisely, my invention consists in interposing resilient supports between the axle and seat, directly or indirectly, and a device for yieldingly resisting movement of the axle and seat from each other, and, with a reservation to myself of such changes in and the yfollowing claims, 4

lVhat I doclaim as new, and desire to secure by Letters Patent, is

1. The combination in a vehicle, of a body, an axle, resilient devices interposed therebetween, a seat, devices interposed be.

tween'said axle and seat of a resilient character, and. means for yieldingly resisting movement of said seat with respect to said axle in one direction.

2. The combination .in a vhicle, of a body, an axle,.resilient means interposed therebetween, a seat, resilient means interposed between said axle and seat permitting their movement toward eachother, and means for yieldingly resisting movement of said axle and seat from each other.

3, The combination. in a vehicle, of a body, an axle, resilient means interposed therebetween, a seat, resilient'means interposed between saidV axle and seat, permittingtheir movement toward. each other,

stopsV for limiting such movement, andv means for yieldingly resisting movement of said axle and seat from each other.

4. The combination in a vehicle, of a body, an axle, resilient means interposed therebetween, a seat, resilient means. inter-` posed between said body and seat, permitting movement toward each other, and means in operative connection with said Copies of this patent maybe obtained flor iive cents each, by'addressing the Commissioner of Patents,

5. .The combination in a vehicle, of a ybody, an axle, resilientfmeans interposed therebetween, a seat, a pivotal support beand means in operative connection with said axle and seat for yieldingly resisting movement of said axle and seat from each other.'

6. The combination ina vehicle, of a body,. an axle, resilient means interposed therebetween, a seat, a pivotal support between body and seat, resilient means interposed. between said axle and seat, and means and means for yieldingly resisting movement of said axle and seat from each other. In testimony whereof I have signed my name to thisl specification in the presence of two subscribing witnesses.
